A discussion of radio communications equipment for personal and family use
The answer to this question is dependent upon a number of factors which include the type of radio system you operate, where you are attempting to cover, how many repeaters or base stations you need …
The issue of exclusive channels is the most critical item in the design and implementation of advanced radio systems. From a legal standpoint, all trunking formats in use today (except for …
When one radio user is transmitting on a radio channel, another radio user can use the radio channel if they are in different areas where there is no coverage overlap. Each radio user can use the …
Different types of data require a different type of network implementation. The discussion in this article is based upon GPS data, but there are many other types of data that are sent over radio and …
There are many different signaling methods for different types of radio systems that have been developed over the years. Each signaling system has its advantages which make the system work …
Antenna site interference is a problem that has plagued the Land Mobile Radio communications business since the inception of two-way radio. There are techniques for operating a clean antenna site so that each radio operates with little to no interference from each other at the site. When properly implemented, these techniques can also reduce or eliminate interference from other radio sites.
Land mobile radio (LMR) started in the 1930s and has made a lot of progress since that time. Originally all LMR radios were one-way radios, because they could only talk in one direction. The …
A trunked radio system, as defined by the FCC is, “A method of operation in which a number of radio frequency channel pairs are assigned to mobiles and base stations in the system for use as a …
